no. 1 Embodiment approach
[0049] figure 1 It is a block diagram showing a configuration example of the object detection device according to the first embodiment of the present invention. exist figure 1 In the composition of , person P is taken as a given detection object. exist figure 1 Among them, 12 is a tag communication unit that receives the tag information sent by the information tag 11 attached to the person P, 13 is an imaging unit that captures an image, and 14 is using the tag information received by the tag communication unit 12 to capture images captured by the imaging unit 13. The object detection unit that detects the person P in the image. The imaging unit 13 is installed at a position where an image including a person P can be captured.
[0050] figure 2 It is a conceptual block diagram showing the internal configuration of the information tag 11 . exist figure 2 Among them, the communication unit 110 communicates with the tag communication unit 12 in a non-contact manner throu...
no. 2 Embodiment approach
[0102] In the second embodiment of the present invention, an object is detected using a mobile robot having a camera as a predetermined detection target.
[0103] Figure 15 It is a figure which shows the situation of this embodiment. Figure 15 In , a mobile robot 40 is placed on the ground FL in the home. The robot 40 as an object detection device includes: the camera 13 serving as an imaging unit; the tag communication unit 12 described in the first embodiment; the object detection unit 14 and the attribute reference unit 15 . In addition, the attribute storage unit 16 is installed in a place different from the robot 40 , and the attribute reference unit 15 refers to the attribute information stored in the attribute storage unit 16 through wireless communication.
[0104] On the floor FL, there are a horizontal cylindrical object Oa and a spherical object Ob. Objects Oa and Ob are both red. Information tags 11 are incorporated in the objects Oa and Ob, respectively, and I...
no. 3 Embodiment approach
[0116] In the third embodiment of the present invention, a person serving as a subject is detected as a given detection target by a portable video camera. The portable cameras mentioned here include portable movie cameras and digital cameras, handheld phones with cameras, and information terminals.
[0117] Figure 20 It is a situation figure which shows this embodiment. exist Figure 20 In this example, the person Pd is photographed outdoors by the portable video camera 50 equipped with the imaging unit 13 . The person Pd has an information tag 11 that transmits ID information that specifies the person Pd as tag information using ultrasonic waves. Generally, when using the ultrasonic transmitter used for measuring the distance, it can detect the range of about 20m from the camera. Of course, the detection range changes according to the intensity of the ultrasonic waves.
[0118] The camera 50 includes: two microphones 51a, 51b; a tag communication unit 12A, and an object...
